hydroxychloroquine and A-V Dissociation

hydroxychloroquine has been researched along with A-V Dissociation in 14 studies

Hydroxychloroquine: A chemotherapeutic agent that acts against erythrocytic forms of malarial parasites. Hydroxychloroquine appears to concentrate in food vacuoles of affected protozoa. It inhibits plasmodial heme polymerase. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p970)
hydroxychloroquine : An aminoquinoline that is chloroquine in which one of the N-ethyl groups is hydroxylated at position 2. An antimalarial with properties similar to chloroquine that acts against erythrocytic forms of malarial parasites, it is mainly used as the sulfate salt for the treatment of lupus erythematosus, rheumatoid arthritis, and light-sensitive skin eruptions.

Fetal Death Not Related to Cardiac Dysfunction

"An autopsy with full evaluation of the heart will be encouraged but cannot be mandated. If AV block or evidence of a cardiomyopathy can be proven, then these will provide the basis for final categorization. If not possible, the death will not be considered a recurrence rate but will be reported." (NCT01379573)
Timeframe: Up to 9 months
